and an integral extension 17 formed on its periphery which is adapted to contact with the projecting studs 13 and l-l and thereby lli oscillate the inner wheel in unison therewith when the said outer wheel is given an oscillating movement to either open or close the draft openings,

Suitably secured at 1S, to one of the panels of tl e outer wheel 7, is a cord, wire or cable 18, which is oassed downward and over a pulley i9 carried by the front plate or memher 3, thence within the hoodwhere it is secured te an eye 2@ formed en the frontend portion of a bar or, ,rod 21,whicli passes through a cylinder 22' suitably arranged within the hood,\the rear end: portion of Asaid rod, 2l passing through an opening *formed in the'dash 2, and terminating with an upright integral handle portion 28, end a downwardly projecting portion 24, whereby said rod may be easily'nianipulated by either the hand or foot, and the lower rear portion of said rod is pro-vided with a' series of notches 25, extending 'tongue 26, forme onthe semicircular plate 27, carried the dash, thereby securing the said rod 1n its adjusted position.

The pulley 19, and the opening therefor in the front plate or frame 3, is protected rom the weather by a shield 28 suitably secured to the outer aceof the plate or frame 3 as shown in Figs. Il and 2.

As will De-seen by reference to Fig. 1, the drafts are shown in the open position creating a free inlet for the cool air, said open position being caused by the rearward movement of the rod 2l by the driver,- which movement causes a downward pull on the cable 'i8' thus iorcing'the extension 17, on

the outer draft wheel 7, to contact with the' stud i3 carried by the inner wheel 6, and carry the inner wheel with the outer wheel until the stud 13 contacts with an upperice cutting device 8,-which constitutes a stop of the further movement of said draft wheels.

The closing operation' for the said draft is performed by a spring 29, the upper end of said spring being secured to a hook or staple 30 secured to one of the panels of the outer draft wheel, while its lower end is suitably secured to a hook 3l attached to the bottom portion of the vfront plate or frame, 3. lt will he readily perceived that when the bar or rod 2l is lifted by the hand or foot of the driver from its engagement with the tongue 26, the tension of the spring 29 will immediately cause a downward movement of the outer draft wheel until its peri heral eXtension l?, contactswith the stud i carried by the inn-er draft wheel, end thus move the infnee unison therewith until the acte lower ice cutting constituting; a stop oet the adapted to enga e the upward mannen further oscillating movement of both draft wheels, larresting their furthermovement, and closing the draft openings It in the front plate or frame.

` While one oi the objects of my improved draft device" is to retain the heat within the hood during extremely cold. weather, and thereby prevent the freezing of the water in the radiator, at the same time through thc operation or" the'oscillating. draft wheels, it is necessary to inake'irequent changes in order to cool the radiator during travel over bad roads, hence to make my invention efcient and practical for night driving,l have provided the draft device with a cylinder 22, which contains a iston 39 through which yand both ends of t e cylinder runen rod 21 said rodbeing,` iixedly secured to the piston. The said cylinder .is provided lat one end with an inlet tube 32E, and toward its other end is provided withan outlet tube 34, the said inlet tube having connected therewith a steam hose 35, which hose is suitably connected at its otherendwithfthe overflow pipe cfa radiator-(notshown). yThe iunc'- 4 tionof this equi ment is when thewaterin,

the radiator 1s' oiling the. steam and hotv -Water will enterthe cylinderthrough the'- steam hose end inlet, and 'force the piston vtoward the opposite end of the cylinder bv yond the outlet tube llgthereby' carrying the manipulating rod 21 with it during its nears.

vward movement thus openingr the ,droit through the medium of the means herein# before asserisce, and thereby inmediately-jm reducing the pressure' within the'oylinder and allowing the steam and .het water to".

escape `through the outlet tube'. By the action of this automatic arrangement the notchedbar. 21 locks itself to the tongue Q16, formed on the plate 27, and when it is desired to close the draft it is simply necessary for the driver 'to trip the lock with his toe or hand., wheny by means of the spring herein referred' to, the draft openings will immediately become closed.

-It will be readily understood that in some makes of automobiles I may prefer to dispense with the use of a spring for performing the closing operation of the draft, and use a weight attached to or carried by a panel near the staple cr hook 30.

It willbe, perceived that the four large openings formed in the front plate or frame for the free admission of air mto'the hood,

are ofless area than the eight panels carried by the two oscillating" draft wheels which it taiaes to cover the four openings, butv this arrangement permits a larger volums of air to circulate through the radiator than a single wheel, since in a single' wheel the panels would beequal in size to the openings and an increased number of panels wou not increase the volume of air 'odmitted, altheugh an increased number et 1 peripheral portionof draft Wheels would increase the `volume of air permitted to. circulate through the radlator.- v

ByV reference to *Ei t will he seen an enlarged view of one o the ice cutting knives r8,l rollided with a vertical extension 36, which `isI xedly secured to the front face of .the front plate or frame 3, and is provided with a right angle forward extension 37, `daptedto overlap the peripheral-portionl both the inner and outer draft wheels, andsterminatingq'in a downward lextension ovided with ice cutting edges and front face of theouter theouter draft Wheel, as clearly shown in Fig. l., 1-
